Do you know that there is a science to eating crayfish? There are those who follow the old ways and those who follow the new ways.

Lao Guai (Yuen Wah) is a traditionalist who invented a method to appease the crayfish and to use the healing power of love. Xiao Yu (Xu Shendong), an internet star, is an advocate of the new ways. Both ways co-exist at a restaurant called Odd Customers. One day, an odd customer does arrive. He is Wind (Kim Kibum), a top star who runs away from the pressure and goes in hiding at the crayfish restaurant, bringing along a whole set of troubles and a mystery killer.
